Xcode 7.3 removed all private frameworks from the SDK. For now, please download iOS 9.2 SDK from https://jbdevs.org/sdks/, extract to Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs and set TARGET to use that, or just download Xcode 7.2 again (https://developer.apple.com/downloads/) and use xcode-select to switch to it.

Thanks! That solved my issue.

Going to reopen this so people coming to report an issue will see it, and becase we do need to find a solution to this.

Im gonna dump shared cache to generate tbds with my new tool machotbd (thanks to @uroboro for help)
@kirb and I have talked about this, but just noting it here.

@kirb When you say set TARGET to use that, I'm not sure exactly what you're referring to. Are you saying set TARGET in the makefile to that directory, or to iPhoneOS9.2.sdk, or something completely different?

@0xdeafcafe Definitely should have explained that more, sorry.

TARGET is a combination of 4 different configuration options related to the platform being built for. The default is iphone:clang:latest:latest, meaning to build for iOS, using clang, with the latest SDK version, deploying to support iOS versions matching the SDK version, or newer. The second argument is a little useless at the moment as the only possible value is clang (or nothing).

In this case, you should edit ~/.theosrc (which probably doesn’t exist, so create it) and insert something along the lines of:

TARGET = iphone::9.2:9.0

Which indicates that you are building for iOS, using SDK 9.2, and intending to support iOS 9.0 and newer.

@kirb ah perfect. all working now. thanks!

hmm.. ive got xcode 7.3 and i downloaded the 9.0 and 9.2 sdks into the SDKs folder.. and then set my ~/.theosrc to TARGET = iphone::9.2:9.0... but it still is complaining and pointing to the 9.3 SDK on make... hmmm... anywhere else to look?

i think im just going to have to go to xcode 7.0.1. sounds like you cannot run older SDKs with 7.3 ... if i remove the other SDKs temporarily.. the compile complains that 9.0 SDK has been skipped because 9.3 is min version.

I'm having the same issue, but I've pointed the TARGET var properly...

Yeah, something isn’t right… will need to look into it. The alternative is SDKVERSION, as I use in my setup here: kirb/dotfiles@6ad4e38

Seems we don't have this problem with Xcode 7.3.1. Please double check to confirm, thanks!

@snakeninny, 7.3.1 didn't bring back private frameworks. If a project successfully links for you, you’re probably just not linking any private frameworks.

https://jbdevs.org/sdks/ appears to be dead. It redirects to youtube. It appears that Xcode 7.2 does not contain the private headers in the SDK anymore either.

@bolencki13 Here is the replacement site: https://sdks.website

Not sure if I am doing it wrong but the headers still don't seem present in the SDK. I checked iOS 9 and it is still throwing an error with #import <Preferences/Preferences.h>

@bolencki13, this header indeed does not exist: https://github.com/theos/headers/tree/master/Preferences. You must import each specific class you’re interested in using.

This will require me to add the headers manually into these include rather than through the SDK?

Private headers were never in the SDK. Public headers are unchanged.

I'm running theos on iOS 9.3.3 and I got the same error when compiling my preference bundle with ios SDK 9.3:

==> Linking bundle xxxPrefs (armv7)…
ld: framework not found Preferences  
clang-3.7: error: linker command failed with exit code 1 (use -v to see invocation) 

However I included the .h files from https://github.com/theos/headers/tree/master/Preferences and added the Preferences.framework to the PrivateFrameworks folder in the SDK.
Also tried to make clean && make package and added the TARGET to ~/.theosrc
I have to compile with the iOS 9.0 SDK in order to let it work.

@MegaCookie, yes, this is what this issue is about. Use of the iOS 9.2 SDK or older is the solution for now.

After following everything in this thread I still couldn't get my project to compile with Preferences. I had one final solution: Terminate the iPhoneOS9.3.sdk symlink.

After that everything compiled and I can see my preferences in Settings.

Just published 9.3 sdk with private frameworks.
mstg/iOS-full-sdk

You can place the sdk folder in $THEOS/sdks and do:

SDKVERSION = 9.3
SYSROOT = $(THEOS)/sdks/iPhoneOS9.3.sdk

in ~/.theosrc

Editing ~/.theosrc with vi command, other command line editor is giving errors.

Is what is described here still the correct and recommended way of dealing with frameworks?

I want to use the iOS 7 SDK and deploy to iOS 7 and up.

To do that I have:

• Added 'TARGET = iphone::7.0:7.0' to my makefile (I only want this project to target iOS 7 and not all of them)
• Downloaded the iOS 7 SDK from sdks.website and placed it in $(THEOS)/sdks/iPhoneOS7.0.sdk
• Added to .theosrc: SDKVERSION = 7.0
• Added to .theosrc: SYSROOT = $(THEOS)/sdks/iPhoneOS7.0.sdk

If I leave any of these steps out, it doesn't work.

Is this how I am supposed to set this up?

It seems strange that I am defining what SDK and deployment target I want to use in the makefile, but then have to do it again in the theosrc globally for all projects.

I have also tried THEOS_PLATFORM_SDK_ROOT, but setting it outside of xcode didn't work either.

I would also prefer to keep the SDKs separately from xcode so that I don't have to redownload them every time xcode is updated.

@KimchaC, yes. Patched SDK (or older SDK) is basically mandatory at this point, unless you avoid linking private frameworks.

At some point I’ll be adding $THEOS/sdks/ to the SDK search path (currently only Xcode.app/…/iPhoneOS.platform/Developer/SDKs/), so after that you’d only need to set the SDK version in $(TARGET).

Thanks, adding $THEOS/sdks/ would be much appreciated.

In case someone else is confused, here is how I set it up without editing theosrc:

• Added 'TARGET = iphone::7.0:7.0' to my makefile (I only want this project to target iOS 7 and not all of them)
• Downloaded the iOS 7 SDK from sdks.website and placed it in $(THEOS)/sdks/iPhoneOS7.0.sdk
• Created a symlink into Xcode's folder: sudo ln -s $THEOS/sdks/iPhoneOS7.0.sdk/ /Applications/Xcode.app//Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/

I followed KimchaC and another error appear:
Your current SYSROOT, “/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk”, appears to be missing. make: *** [before-all] Error 1
Can anyone help me?

That error is because it can't find the sdk. If you tried to make the package before doing all the steps you would have got the same error.

Did you make sure to update the symlink command? I had no problem downloading the 10.1 sdk and creating a symlink with:

sudo ln -s $THEOS/sdks/iPhoneOS10.1.sdk/ /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs

Note there isn't a double // between Xcode.app/Contents, and there is a space between iphoneOS10.1sdk/ and /applications.

Make sure theos is up to date as well.

You should avoid modifying Xcode.app, and I’m pretty sure you can’t anyway as of Xcode 8 when SIP is enabled. Set SDKVERSION and SYSROOT in .theosrc as described in #146 (comment).

As of bcd16b4, we now scan for SDKs in both Xcode.app and theos/sdks/. There is currently an issue with the logic that determines the latest available SDK, where 10.1 will be seen as older than 9.3 (but 8.4 is older than 9.3 as expected), which will be fun to fix since macOS’s ancient sort doesn’t have the -V flag. Of course, if you’re using the patched iPhoneOS10.1.sdk, while Xcode 8.2 is installed, you’ll still need to manually specify your SDK version using TARGET; otherwise Theos will use iPhoneOS10.2.sdk because it’s newer. This also only applies to iOS targets at this point (see #242).

Despite the bugs, I’m considering this fixed. Will add details on downloading/setting up a patched SDK to the installation wiki page.
