Hi,

I got this issue while trying to build my app on AppCenter

CompileSwift normal armv7 (in target 'McPicker' from project 'Pods')
cd /Users/runner/work/1/s/YourFut/Pods
/Applications/Xcode_11.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift -frontend -emit-bc /Users/runner/work/1/s/YourFut/Pods/McPicker/McPicker/Classes/McPicker.swift /Users/runner/work/1/s/YourFut/Pods/McPicker/McPicker/Classes/McPickerBarButtonItem.swift /Users/runner/work/1/s/YourFut/Pods/McPicker/McPicker/Classes/McPickerPopoverViewController.swift /Users/runner/work/1/s/YourFut/Pods/McPicker/McPicker/Classes/McTextField.swift -emit-module-path /Users/runner/Library/Developer/Xcode/DerivedData/YourFut-bcgsjxzsmxluocadjionpbjzwutd/Build/Intermediates.noindex/ArchiveIntermediates/YourFut/IntermediateBuildFilesPath/Pods.build/Release-iphoneos/McPicker.build/Objects-normal/armv7/McPicker.swiftmodule -emit-module-doc-path /Users/runner/Library/Developer/Xcode/DerivedData/YourFut-bcgsjxzsmxluocadjionpbjzwutd/Build/Intermediates.noindex/ArchiveIntermediates/YourFut/IntermediateBuildFilesPath/Pods.build/Release-iphoneos/McPicker.build/Objects-normal/armv7/McPicker.swiftdoc -serialize-...
