Answer

It seems that the pod gem (the package manager for Swift and Objective-C projects) is not installed. Fix it with:

$ sudo gem install cocoapods
$ cordova plugin add cordova-plugin-lottie-splashscreen

Manifest merger failed

> Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
  	is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
  	Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:5:5-12:19 to override.

** BUILD FAILED **

Answer

Add the following preference to the config.xml iOS section: <preference name="SwiftVersion" value="5" />.

error: SWIFT_VERSION '5.0' is unsupported, supported versions are: 3.0, 4.0, 4.2. (in target 'lottie-ios')

error: SWIFT_VERSION '5.0' is unsupported, supported versions are: 3.0, 4.0, 4.2. (in target 'lottie-ios')

Answer

Make sure to set a valid SwiftVersion value. For Swift 5 it is 5 and not 5.0. Please make sure to use a recent Xcode version that supports the desired Swift version, too.

Help my background color is not displayed correctly on Android

If you experience wrong background colors on Android, especially with leading zeros, you've probably ran into an internal Android issue (AAPT2 parsing bug) that swallows leading zeros and changes the color value.

Answer

You can add a build-extras.gradle file in the platforms/android folder with the following content to workaround the issue:

android {
    aaptOptions {
        additionalParameters "--keep-raw-values"
    }
}

xcode-select is a command line tools instance

xcodebuild: Command failed with exit code 1 Error output:
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

Answer

You need to make sure to install Xcode and re-link the command line tools: sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
