I Create custom button apple Sign up apple, error in here code:

private func setupSignUpWithAppleButton() {

        let signUpWithAppleButton: SignInAppleButton = SignInAppleButton()

        signUpWithAppleButton.addTarget(self, action: #selector(didTapSignUpWithAppleButton(_:)), for: .touchUpInside)

        subView.addSubview(signUpWithAppleButton)

        signUpWithAppleButton.fillInSuperview()

    }

This fixing code, with change addTarget to  tap Gesture 

  private func setupSignUpWithAppleButton() {

        let signUpWithAppleButton: SignInAppleButton = SignInAppleButton()

        subView.addSubview(signUpWithAppleButton)

        signUpWithAppleButton.fillInSuperview()

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(didTapSignUpWithAppleButton))

        signUpWithAppleButton.addGestureRecognizer(tapGesture)

    }

this full custom UIButton

public final class SignInAppleButton: UIButton {

    private lazy var containerView: UIView = {

        let view: UIView = UIView()

        view.translatesAutoresizingMaskIntoConstraints = false

        view.backgroundColor = .clear

        return view

    }()

    private lazy var appleLogoImageView: UIImageView = {

        let imageView: UIImageView = UIImageView()

        imageView.translatesAutoresizingMaskIntoConstraints = false

        imageView.image = UIImage(named: "appleLogo")?.withRenderingMode(.alwaysTemplate)

        imageView.tintColor = .white

        imageView.contentMode = .scaleAspectFit

        return imageView

    }()

    private lazy var textLabel: UILabel = {

        let label: UILabel = UILabel()

        label.translatesAutoresizingMaskIntoConstraints = false

        label.font = .systemFont(ofSize: 16, weight: .medium)

        label.textColor = .white

        return label

    }()

    public init() {

        super.init(frame: .zero)

        setupViews()

    }

    required init?(coder: NSCoder) {

        fatalError("init(coder:) has not been implemented")

    }

    private func setupViews() {

        backgroundColor = .black

        layer.cornerRadius = 6.0

        addSubview(containerView)

        containerView.addSubview(appleLogoImageView)

        containerView.addSubview(textLabel)

        NSLayoutConstraint.activate([

        ])

        textLabel.text = "Sign up with Apple"

        layoutIfNeeded()

    }

}

 This error when run Unit testing file ex: EditSettingsTests

Unable to load contents of file list: '/Target Support Files/FBAEMKit/FBAEMKit-xcframeworks-input-files.xcfilelist'

Unable to load contents of file list: '/Target Support Files/FBSDKCoreKit_Basics/FBSDKCoreKit_Basics-xcframeworks-input-files.xcfilelist'

How to fixing 

1. in 'SettingsTests' set pod like 'Settings' and 'pod install'

example:

# MARK: - Settings

target 'Settings' do

  project 'Features/Settings/Settings'

  pod('FBSDKLoginKit', '12.1.0')

end

# MARK: - SettingsDemo /SettingTests

target 'SettingsDemo' do

  project 'Features/Settings/Settings'

  pod('FBSDKLoginKit', '12.1.0')

  target 'SettingsTests' do

    inherit! :complete

  end

endend

2. in scheme Change 'SettingsTests' and then select edit scheme 

   - tab 'Run' change build configuration from 'Development' to 'Debug(Development)'

   - tab 'Test' change build configuration from 'Development' to 'Debug(Development)'

   - tab 'Profile' change build configuration from 'Production' to 'Adhoc(Production)'

   - tab 'Analyze' change build configuration from 'Production' to 'Adhoc(Production)'

   - tab 'Archive' change build configuration from 'Production' to 'Adhoc(Production)'

   and then 'pod install' again

Note: in Build do not change

3. Run 'SettingsTests' file ex: 'EditSettingsTests'

When work in a project get Errors and how I solve the errors in xcode, Pod, terminal, github, swift code and crash app will be here.


 1. "Pod install" Error

Check this Error screenshot

libc++abi.dylib: terminating with uncaught exception of type NSException
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Mutating a priority from required to not on an installed constraint (or vice-versa) is not supported. You passed priority 500 and the existing priority was 1000.'

try to Debug

Debug
(lldb) po descFirstHeight.priority
▿ UILayoutPriority
- rawValue : 1000.0

(lldb) po descSecondHeight.priority
▿ UILayoutPriority
- rawValue : 500.0

(lldb) po UILayoutPriority.defaultLow
▿ UILayoutPriority
- rawValue : 250.0

(lldb) po UILayoutPriority.defaultHigh
▿ UILayoutPriority
- rawValue : 750.0

(lldb)

Solution
- In XIB dont set (priority = 1000) but you must set (prority = 999)
descFirstHeight =  999
descSecondHeight = 250

- And in file swift 

descFirstHeight.priority = UILayoutPriority.defaultLow // 250

descSecondHeight.priority = UILayoutPriority.defaultHigh // 750

3. In Stackview cannot change color UIView (IOS 12)

Condition when subview in stackview 

example look like this

in phone 8 (IOS 12)

Should be like this
in Iphone 11 (IOS 15)

let see the code Before, it is because in ios 12 the process is slower than ios 15 

//// Code here ///

    private func updateDigitView(_ digitView: UIView, isHighlight: Bool) {

            digitView.backgroundColor = isHighlight ? .cyan : .clear

            

            if let bulletView = digitView.subviews.last {

                bulletView.backgroundColor = isHighlight ? .blue : .clear

                bulletView.layer.borderWidth = isHighlight ? 0 : 1

                bulletView.layer.borderColor = isHighlight ? nil : UIColor.cyan.cgColor

            }

    }

//// ----------- ///

SOLUTION

So this my solution can fix that problem use dispatchqueue async

//// Code here ///

 private func updateDigitView(_ digitView: UIView, isHighlight: Bool) {

     DispatchQueue.main.async {

            digitView.backgroundColor = isHighlight ? .cyan : .clear

            

            if let bulletView = digitView.subviews.last {

                bulletView.backgroundColor = isHighlight ? .blue : .clear

                bulletView.layer.borderWidth = isHighlight ? 0 : 1

                bulletView.layer.borderColor = isHighlight ? nil : UIColor.cyan.cgColor

            }

        }

    }

//// ----------- ///

4. Error build after (pod install)

error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.

How to Solve

- clean build/ delete DrivedData

- pod install / pod update (again)

If still an error

- checkout to branch development/master and build app.
- If in branch master not failed back into your branch and build your app again

5. UserDefaults JSON
this example use pod swiftyJson

// set

if let model = JSON["data"].rawString(.utf8, options: .fragmentsAllowed) {

  UserDefaults.standard.setValue(model, forKey: "UserDefaultKey")

 }

//call

guard let status = UserDefaults.standard.string(forKey: "UserDefaultKey"), let data = statusOA.data(using: .utf8) else {

return nil }

6. Nil when passing data Model

When I passing optional data model like this 
example: 

In Model

struct Form: Codable {

var isValue: Bool?

var isUsed: Bool?

enum CodingKeys: String, CodingKey {

case isValue, isUsed

}

init(from decoder: Decoder) throws {

let container = try decoder.container(keyedBy: CodingKeys.self)

isUsed = try container.decodeIfPresent(Bool.self, forKey: .isUsed)

isValue = try container.decodeIfPresent(Bool.self, forKey: .isValue)

}

}

In View Controller

var form: Form?

//When Passing from API Response

.

.

.

form = response?.form

.

.

.

print(form.isValue) // nil

Solution is  create a new request model with parameter

struct FormModel {

struct Request {

var parameters: [String: String]?

public init(isValue: Bool, isUsed: Bool) {

parameters = [

"isValue": "\(isValue)",

"isUsed": "\(isUsed)"

]

}

}

}

/////------/////------/////------/////------/////------

// in viewDidLoad example

form = FormModel.Request(isValue: true, isUsed: false)

// now is not nil

7. Error Need Install `cocoapods-keys`

Not running with Xcode Cloud, setup podfile with cocoapod-keys plugin

[!] Your Podfile requires that the plugin `cocoapods-keys` be installed. Please install it and try installation again.

The problem is my git change from `https` to `ssh` setting so my old version ruby is `2.6.1` update to `3.1.2`

Solution

- delete old `cocoapod-keys-App ` in Keychain access

$arch 

$ruby -v   

$brew     

$brew install rbenv ruby-build

$rbenv install 3.1.2  

$rbenv global 3.1.2    

$open ~/.zshrc  

$ruby -v 

$gem install cocoapods-keys

$gem install cocoapods

$gem install fastlane

$cd app    

$pod install 

8. When Cannot Run "xed ." in terminal  

This Error

app: $xcode-select --install

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

Solution:

xcode-select --install

sudo xcode-select -s /Applications/Xcode.app/Contents/Developersudo xcodebuild -license accept
