AppCode 2018.1 Swift + Objective-C project is unusable.


After upgrading to 2018.1 the project which I work is unusable. 

it is constantly freezing, I click on something and freezes for around 10 seconds. I work more 5 seconds, click on something, and more 10 seconds froze.

I work on a very big a complex project mixing Objective-C and Swift. It is enabled the tracking for AppCode improvements. 

It is sad because I really like the project and would like to use it more, but have to switch to XCode which I don't like, because of performance issues.

Hi Guilherme.

Could you please submit logs (collected via Help | Show Log in Finder) to our support email:

Hi Tatiana,

thanks for your quickly answer.

I sent the part of the logs to that email. As I said in the email, I have 3gb of logs in that folder, so I got just a few. 


I'm experiencing this too. In the past this has been fixed by updating my JVM properties to use more memory. But the app is actually using fairly little of the 12GB I've allowed it.

Guilherme Endres -- if you haven't updated your JVM properties you should try that.


Hi Christian, 

I did update yesterday. It helped but I have not tried extensively to check if the problem still persists. 

But also it should not freeze constantly, even with low memory allocated (2gb). 



Guys, according to the info provided (logs, etc), you're experiencing different issues.

Problem that Guilherme sees it tracked in OC-16793

Christian, let's continue discussion in support - not 100% clear yet what's going on.
