iOS15 beta版本安装不成功 || app要求更新

一、原因:缺少DER entitlement

解释一下DER:DER is short fro Distinguished Encoding Rules and is a standard by which ASN.1 structures are transferred. ASN.1 is a standard by which data can be encoded and decoded no matter which platform is being used. ASN.1 in this specific case applies to data encoding

简单的说就是一种加密方式。

二、错误提示:validation failed because of missing DER entitlements

[MICodeSigningVerifier _validateSignatureAndCopyInfoForURL:withOptions:error:]: 74: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.xbDKXR/extracted/Payload/*********.app : 0xe8008029 (The code signature version is no longer supported.)

三、解决办法:

3.1、看自己的macOS的系统版本:如果是macOS Big Sur or macOS Monterey,那么直接加上flag:--generate-entitlement-der 即可,

        【怎么加--generate-entitlement-der】:<1> xcode中build setting 中OTHER_CODE_SIGN_FLAGS:--generate-entitlement-der 

<2> re-sign,这个对单个APP可以

# Re-sign your app

% codesign -s "Signing Identity Name from Keychain" -f --preserve-metadata --generate-entitlement-der MyApp.app
...
MyApp.app: replacing existing signature

# Check your signature again

% codesign -dvvvvv  ActionExtensionHostSSO.app
...

3.2 如果macOS Mojave and Catalina以下的,在xcode下也可以编译成功,然后打包payload成ipa也可以安装。但是在archive下直接生成ipa不行,

这个必须就要升级macOS的系统了。因为这个--generate-entitlement-der新flag。
