ios - 使用dylib创建ios框架

Question

我有 60k 行 pascal 代码(不要问:-))。使用free pascal为armv7和aarch64编译了dylib。它可以在设备上运行，但在以下情况下无法将其上传到应用商店

Invalid Swift Support - The SwiftSupport folder is missing. Rebuild your app using the current public (GM) version of Xcode and resubmit it.

这意味着

Dynamic libraries outside of a framework bundle, which typically have the file extension .dylib, are not supported on iOS, watchOS, or tvOS, except for the system Swift libraries provided by Xcode (tn2435).

所以，根据这个，应该有一种方法可以用dylib创建一个框架。此外，还有很多带有库的框架:Fabric、Crashlytics、Firebase、GoogleAnalytics 等。

我研究了这个框架并创建了自己的框架。但现在我有错误

The binary file 'test.dylib' is not permitted. Your app can’t contain standalone executables or libraries, other than the CFBundleExecutable of supported bundles.

所以，我的问题是如何使用 dylib 创建一个框架(使用 Function test(foo:integer):integer;cdecl;)，加载它并在 ObjectiveC 项目中使用？

谢谢。

使用 free pascal 编译了适用于 armv7 和 aarch64 的 dylib。 dlopen() 运行良好，但无法上传到应用商店。

尝试制作简单的框架，但是

The binary file 'test.dylib' is not permitted. Your app can’t contain standalone executables or libraries, other than the CFBundleExecutable of supported bundles.

library fpctest;

{$ifdef fpc}
 {$mode delphi}
{$endif}

uses sysutils;

Function test (foo: integer) : integer; cdecl;
begin
  Result := foo * 2;
end;

Exports
  test;
end.

需要 dylib 的工作框架。

注释掉了项目特定部分。您可以通过创建一个虚拟框架并从那里复制来获取 Info.plist 和 DSYM Info.plist。

# set OUT_DIR and LIB_NAME
FW_PATH="$OUT_DIR/$LIB_NAME.framework"
INFO_PLIST="$FW_PATH/Info.plist"
OUT_DYLIB="$FW_PATH/$LIB_NAME"

# set the DYLIBS, SOURCE_INFO_PLIST and HEADER_PATH for the library
mkdir -p "$FW_PATH"
cp "$SOURCE_INFO_PLIST" "$INFO_PLIST"
lipo $DYLIBS -output "$OUT_DYLIB" -create
mkdir -p "$FW_PATH/Headers"
cp "$HEADER_PATH" "$FW_PATH/Headers"
install_name_tool -id @rpath/$LIB_NAME.framework/$LIB_NAME "$OUT_DYLIB"

# set the DYLIBS and SOURCE_INFO_PLIST for DSYM
OUT_DSYM_PATH="$FW_PATH.dSYM/Contents/Resources/DWARF"
INFO_PLIST="$FW_PATH.dSYM/Contents/Info.plist"
mkdir -p "$OUT_DSYM_PATH"
cp "$SOURCE_INFO_PLIST" "$INFO_PLIST"
lipo $DYLIBS -output "$OUT_DSYM_PATH/$LIB_NAME" -create
