Xcode项目:构建失败 [英] Xcode project: Build Failed

问题描述

我试图构建新项目，但是当我单击build时，构建每次都会失败.

I tried to build my new project, but when I click build, the build fails every time.

我尝试删除我的项目并再次创建它，但是仍然没有帮助.

I tried deleting my project and made it again, but it did not help anyway.

警告

:-1: Capabilities for MyFirstApp may not function correctly because its entitlements use a placeholder team ID. To resolve this, select a development team in the build settings editor. (in target 'MyFirstApp')

错误

~/MyFirstApp/Base.lproj/LaunchScreen.storyboard:-1: Failed to find or create execution context for description '<IBCocoaTouchPlatformToolDescription: 0x7fc3a9a03e10> System content for IBCocoaTouchFramework-ElevenAndLater <IBScaleFactorDeviceTypeDescription: 0x7fc3a9a141a0> scaleFactor=2x'. These intermediate objects were non-nil: (

这些是Xcode向我显示的错误消息.项目名称为"MyFirstApp"，我在该错误消息上剪切了一些文件路径.那我怎么建这个项目呢?

These are the error messages that Xcode showed me. The project name was 'MyFirstApp' and I cut some file paths on that error messages. So how can I build this project?
