Current behavior:
I upgraded to 3.7.1 from 3.6.0 and noticed that the toolbar on iOS now overlaps the statusbar. Image below:

Expected behavior:
The toolbar should not overlap the statusbar. Image below shows how it should be. (from before upgrading)

I upgraded from 3.6.0 to 3.7.1.

Hello! Thank you for opening an issue with us! Would you be able to provide a sample application via GitHub that demonstrates the issue you are having? Thanks for using Ionic!
Hello! I have the same issue with the "tabs" starter project. To reproduce:
$ ionic start my-tabs tabs
$ cd ./my-tabs
$ ionic lab
If I open the lab url with Safari (v11.0), I have the issue:

However, if I open the lab url with Chrome (v61.0.3163.100), no issues:

I tested with Ionic view and I have the issue on iPhone 7 IOS v11.0.3.
@kensodemann I can confirm that this happens with a newly started project as demonstrated by @levesquejf. It does not happen on Chrome, only Safari.
Just wanted to chime in and confirm that we've noticed the same issues on 3.7.1 but only after updating to iOS 11. I assume that's relevant.
I have a hunch these are also related: #13152 #13160
I experienced the exact same issue.
I opened issue 24 and it looks like it is happening on ALL projects (existing and new) after upgrading to WKWEBVIEW and iOS 11. Screenshots below are from an iPhone 7 plus
Conference app

Tabs starter app

Thank you for the issue report. So there are a few things happening here...
1) The statusbar padding being off in safari/ionic-lab but not in chrome.
The new releases of Ionic (3.7 and up) use the css constant/env features in iOS/Safari. This is how we can properly size the header on iOS 11 and iPhone X without any issues. Since this is supported in Safari, it just happens to work in lab, but is set to 0. Will have to fix this on the Lab side of things.
2) App deployed to Device/sim not sized correctly.
This Im not able to recreate myself actually. I have started a blank tabs app, upgraded to the latest nightly build of ionic-angular (which includes more ios11 list fixes) and deployed to iPhone-7-Plus and it works as expected. This includes the latest WKWebview as well.

If someone can provide a clear list of steps or starter project that can recreate this issue, that would be great.
@mhartington you mentioned you upgraded to the latest nightly build. What do I need to do to upgrade to the latest nightly build? If that doesn't fix the issue I can give you access to my private repo where you should be able to recreate it
upgraded to the latest nightly build of ionic-angular (which includes more ios11 list fixes)
npm i ionic-angular@nightly @ionic/app-scripts@nightly
@mhartington I'm getting all kinds of errors after I upgraded to latest nightly. Let me give you access to my repo.

Those are mostly lint errors.
I was able to run your app without any issues.

And everything worked as expected.
I have a public repo that has this issue: https://github.com/jbw91/toolbar-issue
Here's my environment info from running ionic info:

Here is a screenshot from my iPhone 7 Plus device I ran it on using ionic cordova run ios --livereload
And here is a screenshot of me running it in an emulator after building the project with ionic cordova build ios

@jbw91 Your app was missing several important things.
1) Viewport fit: you're viewport meta tag is missing viewport-fit=cover
2) Statusbar plugin: You're using the older plugin which does not contain fix required
This is cover in the iOS 11 Checklist blog post
Updating those 2 things produces this.

Yep that was it. I was just following the Ionic CHANGELOG, didn't see the blog post. Good to know. Thanks.
@mhartington
