mac安装homebrew,xcode报错

由 半城伤御伤魂 提交于 2020-12-11 13:30:33
环境：mac10.15.6 安装homebrew时报错 具体错误： no developer tools were found at ‘/Applications/Xcode.app’, requesting install. Choose an option in the dialog to download the command line developer tools. 报错原因：mac没有装xcode，xcode居然有11个G 解决方法：其实不需要下xcode，只需要下一个xcode的管理工具（个人理解），而且只有不到800M（亲测有效） 下载地址：https://developer.apple.com/download/more/ 再次执行安装命令就可以了 /usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)” 完成~ 来源： oschina 链接： https://my.oschina.net/u/4412439/blog/4791880

What does 'identity' mean in SwifUI and how do we change the 'identity' of something

问题 I'm new to SwiftUI and I'm having problems with presenting Alerts back-to-back. The description of the .alert(item:content:) modifier has this written in it's definition: /// Presents an alert. /// /// - Parameters: /// - item: A `Binding` to an optional source of truth for the `Alert`. /// When representing a non-nil item, the system uses `content` to /// create an alert representation of the item. /// /// If the identity changes, the system will dismiss a /// currently-presented alert and

问题 What is the use of "Preview Assets" assets catalog in Xcode 11 beta? I have just created new project with SwiftUI. I have checked release notes of Xcode 11 beta but there is no information about this assets catalog. What is the use of it? 回答1: Now, when you layout your views you can preview it in Canvas (the window from the right side of the code editor). Obviously, some images and other data for your app you can get only in runtime, from your API for example. So all stubs can be placed into

问题 Running Xcode 12, my Swift 5 Xcode project now has warnings whenever a Decodable or Codable type declares a let constant with an initial value. struct ExampleItem: Decodable { let number: Int = 42 // warning } Immutable property will not be decoded because it is declared with an initial value which cannot be overwritten Xcode suggests changing the let to a var : Fix: Make the property mutable instead var number: Int = 42 It also suggests the fix: Fix: Set the initial value via the initializer

ERROR: Apple silicon Macs support issue. The app has LSApplicationLaunchProhibited set to true. This is not supported on Mac, How to fix it?

问题 I got this error while trying to submit a stickerpack to the AppStore: WARNING ITMS-90863: "Apple silicon Macs support issue. The app has LSApplicationLaunchProhibited set to true. This is not supported on Mac." The stickerpack is not intended to be used in Macs, it is only for Iphones and Ipads? How can I remove this warning so that I can upload it successfully ? because I also got this email afterwards: We identified one or more issues with a recent delivery for your app, "Name of the App".
