iOSでEXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0) が発生する

2016/09/22

iOS 10（シミュレーター）で「EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)」でアプリが強制終了する。
Xcode8にはこのメッセージが出ている。

This app has crashed because it attempted to access privacy-sensitive data without a usage description.  The app's Info.plist must contain an NSPhotoLibraryUsageDescription key with a string value explaining to the user how the app uses this data.

どうやら、 Photo Libraryを使うにはアプリに“Privacy - Photo Library Usage Description”の設定が必要なようだ。

NSPhotoLibraryUsageDescription “Privacy - Photo Library Usage Description” Specifies the reason for your app to access the user’s photo library. See NSPhotoLibraryUsageDescription for details. Cocoa Keys Cocoa Keys

ということでInfo.plistにNSPhotoLibraryUsageDescriptionを入れてみたところエラーは解消した。

Info.plist

<key>NSPhotoLibraryUsageDescription</key>
	<string>for photo edit and store.</string>
