error HE0004: Could not load the framework 'IDEDistribution'

The same issue here. Macbook M1 with xcode 16.1 and Rider 2024.3

Same issue in my case too. I have trying to figure it out for 3 days already. Tried different combinations of dotnet+maui, xamarin ios, xcode versions. Nothing helps.

Tried last resort - rollback to previous version of Rider. It helped.

Here is my configuration in case it's gonna help somebody else too.

MacOS: 15.1.1 (24B91)

dotnet: 8.0.403

maui: 8.0.83/8.0.100

Xamarin.iOS: 16.0.4.83

xCode: 16.1.0

Rider: 2024.2.7

It built, deployed and started my app with debugger attached.

Found this – helpful – sort of.  Looks like a patch for 2024.3 will fix this as noted at the end of the thread 1 day ago.

https://youtrack.jetbrains.com/issue/RIDER-117599

In my case I ended up with visual studio code as a debugger  for IOS. The rest can be handled by Rider. 

it was working fine for me until I updated to Rider 2024.3, now it wont run on iOS. one workaround is to run the app from VS Code using the MAUI extension.

That is a great news! Thanks!

Can you give a timeline when 2024.3.1 will be released?

In my case, I can compile, but then I can't actually use the new build to debug with, but it is the same exact error.  I probably don't need to say it, but I will.  This is a really bad bug and we need a fix ASAP.

Dmitry Kazantsev 

Its terrible to read from you that Rider has effectively broken iOS development, but oh btw, we'll release a fix in month!  This version of Rider has effectively shutdown iOS development for users and subscribers (like me).

Awful, awful, awful.  I'd advise you to reach out to your team and ask them to release a patch for this ASAP (like today!).

Hello Jason,

I understand your concerns about the situation. Take my sincere apologies for any inconvenience caused by this. I did my best to bring team attention to this problem.

The fix is now available in the Nightly build. You can get it from the ToolBox app via Rider | … | Other Versions:

Have a nice day!

Dmitry Kazantsev,

We are blocked with iOS development for maui project. The Nightly build also not working. Can you provide the steps to solve this.

Sandeep Kumar ,

I am sorry to hear you are running this issue. I noticed you mentioned the Rider version as "JetBrains Rider 2024.3 EAP 6 D". Early-Access period has already been ended. Would you mind trying the Nightly version of Rider and verifying if the issue persists? Here is the instruction: SUPPORT-A-552 How to install Nightly build for Rider

Have a nice day!

Dmitry Kazantsev,

I have updated the rider and below is Rider version details and I'm facing same issue. No Luck. 

Note: I see the issue is getting with is .Net 7.0 MAUI project only.

JetBrains Rider 2024.3 EAP 6 D
Build #RD-243.23142, built on December 3, 2024
Runtime version: 21.0.5+8-b631.28 aarch64 (JCEF 122.1.9)
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.
Toolkit: sun.lwawt.macosx.LWCToolkit

 

Sandeep Kumar ,

Thank you for double-checking. This is indeed the actual Nightly build. Would you mind also submitting another issue as per the steps I described above?

With the nightly build #RD-243.23189 I solved my problem.

The problem only occurs running debug on IOS Simulator; no problem if I run the project with the Mac OS target.

My setup:

1) basic Maui Blazor Hybrid empty project create with the scaffolding

2) .Net 9.0.101

3) Macbook pro M2 Max Sequoia 15.1.1

E Zambrano , Do you still get the same error message Could not load the framework 'IDEDistribution' when trying to launch app in iOS simulator (in the latest Nightly build), or is there another error?
If you can't launch MAUI project with iOS target in the latest Nightly, would you mind submitting another issue to our tracker and attaching additional information as described below?

• Go to Help | Diagnostic tools | Choose Trace Scenarios;
• Enable the trace scenario for MultiPlatform;

Dmitry Kazantsev My error is: “error HE0004: Could not load the framework 'ContentDeliveryServices'”

The error occurs only with release #RD-243.21565.191

With the Nightly Build, no problems occur.

I'm facing this issue when trying to run .Net iOS app on iPhone and simulator. Below are the configurations

JetBrains Rider 2024.3.3

XCode 16.2

I am also facing exact issue on JetBrains Rider 2024.3.3  / XCode 16.2 

This is extremely annoying 

we are not using Maui but Native .net “NET7.0-ios” 

Still happening!

Jvillaro, I noticed you are running Rider on x86_64 runtime. If your Mac machine is M1/2/3-based, please ensure to install an Apple Silicon version of Rider:

If your Mac is x64 based, or installing a proper Rider version doesn't help, please submit a bug report too.

Have a nice day!

Is there any update on if Rider can support XCode 16.2 ? I would post all the versions and my setup, but I just need to know if any person out there can even run Rider on Mac with Xcode 16.2. Rider can not find any simulators, ive done all the workarounds and hacks that people say try and nothing is working. I am using latest Rider version

Dmitry Kazantsev 

I wouldnt care so much but I am paying for this!

Hello Ryan,

Yes, I was able to make it work. I installed XCode 16.2 together with the iOS 18.2 + iOS 18.3.1 platform support, selected it via sudo xcode-select /Applications/Xcode16.2.app/Contents/Developer, accepted license (sudo xcodebuild -license), and rebooted the machine. I installed iOS workload using latest .Net 9 installation (sudo workload install ios). I then checked if simulators are available for the sample .NET 9.0 iOS project. 

Unfortunately, it didn't work out of the box, and no simulators were shown in Rider.

I found that the simulator runtime for iOS-18-2 is missing (xcrun simctl list runtimes), so that I installed that xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion 18.2. (You can also do it from XCode settings):

Once it got installed, I opened Rider and simulators got discovered fine. I was able to run a sample project (targeting net9.0-ios) in a simulator.

I suggest you try the same steps. If that doesn't help, I would appreciate it if you could submit a bug report as per instructions I described above.

Have a nice day!

I'm experiencing this issue on 2024.3.6 and Xcode 16.2, 18.2 simulators, MBP M4, Sequoia 15.3.1

Dmitry Kazantsev 's solution didn't work for me was I had all the workloads and build tools installed
