iOS 应用安装失败问题

万能步骤:

• 清理Xcode缓存
• 清理模拟器缓存
• 重启Xcode
• 重新配对手机

无法链接设备

1. 错误 dyld_shared_cache_extract_dylibs failed ,将手机链接记录删除后重新配对认证。
2. 间歇性链接不上

检查数据线是否OK,检查手机是否信任电脑.

Flutter EXC_BAD_ACCESS (SIGKILL - CODESIGNING)

iOS 14 构建Flutter debug环境的应用失败

和签名有关,切换成 release模式就ok了，网上说法是和adhoc证书,不支持debug模式打包有关 https://stackoverflow.com/questions/58814361/how-to-fix-termination-reason-namespace-codesigning-code-0x2-error-in-flutte?r=SearchResults

3. Building for iOS Simulator, but linking in dylib built for iOS, file '/Users/qxq4633/mobile-connected/ios/Flutter/Flutter.framework/Flutter' for architecture arm64
   今天升级Xcode 12后运行Flutter工程,模拟器下缺出现了arm64，于是检查 buildSettings配置发现 Pod工程中默认将Build Active Architecture设置为NO,于是修改为Yes,防止打包真机架构,可结果却还是报错,于是打印环境变量,发现Code默认将arm64设置为当前使用架构,模拟器也能执行

    ARCHS_STANDARD = arm64
    ARCHS_STANDARD_32_64_BIT = armv7 arm64
    ARCHS_STANDARD_64_BIT = arm64
    ARCHS_STANDARD_INCLUDING_64_BIT = arm64
    ARCHS_UNIVERSAL_IPHONE_OS = armv7 arm64
    PLATFORM_PREFERRED_ARCH = arm64
    VALID_ARCHS = arm64 arm64e armv7 armv7s

将工程中定义了EXCLUDED_ARCHS = arm64,排除就ok了
