To build for macOS, just follow the
<a href="#installation">regular instructions</a> above.
To build for iOS, follow the regular instructions, but instead of
`./configure` do something like this:
$ clang="clang -isysroot $(xcrun --sdk iphoneos --show-sdk-path)"
$ export OBJC="$clang -arch armv7 -arch arm64"
$ export OBJCPP="$clang -arch armv7 -E"
$ export IPHONEOS_DEPLOYMENT_TARGET="9.0"
$ ./configure --prefix=/usr/local/ios --host=arm64-apple-darwin
To build for the iOS simulator, follow the regular instructions, but instead
of `./configure` use something like this:
$ clang="clang -isysroot $(xcrun --sdk iphonesimulator --show-sdk-path)"
$ export OBJC="$clang -arch arm64 -arch x86_64"
$ export OBJCPP="$clang -arch arm64 -E"
$ export IPHONEOS_DEPLOYMENT_TARGET="9.0"
$ ./configure --prefix=/usr/local/iossim --host=arm64-apple-darwin
<h3 id="framework-in-xcode">Using the macOS or iOS framework in Xcode</h3>
To use the macOS framework in Xcode, you need to add the `.framework`s to
your project and add the following flags to `Other C Flags`:
-fconstant-string-class=OFConstantString -fno-constant-cfstrings

<h1 id="first-app">Writing your first application with ObjFW</h1>
To create your first, empty application, you can use `objfw-new`:
$ objfw-new --app MyFirstApp
This creates a file `MyFirstApp.m`. The `-[applicationDidFinishLaunching]`
method is called as soon as ObjFW finished all initialization. Use this as
the entry point to your own code. For example, you could add the following
line there to create a "Hello World":
[OFStdOut writeLine: @"Hello World!"];
You can compile your new app using `objfw-compile`:
