Instantiating HMHomeManager causes a background thread error

I have a fresh iOS app / project; all I've done is import the HomeKit framework. When I instantiate HMHomeManager:



var homeManager = HMHomeManager()


Xcode yells at me:



Main Thread Checker: UI API called on a background thread: -[UIApplication applicationState]


... this occurs even if I wrap it in DispatchQueue.main.async {}



Since this project is effectively blank, I'm assuming this an Xcode bug ... but am I doing something wrong?

  • Can you show more context? Where are you instantiating the HMHomeManager? Which version of iOS and Xcode are you using? I just created a blank single view application in Xcode and instantiated a HMHomeManager both as a property with a default value and in viewDidLoad and did not have any warnings on background thread.

  • @Paulw11 Xcode version 10.1 (10B61) ... iOS 12.1 (16B92) ... doing exactly the same thing you are.

  • Hmm. I am running the same versions. I tested on an iPhone 8+ and an iPhone XR simulator. No issues. Can you upload your test project somewhere?

Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

Image
up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title. Any help appreciated, as always. documentclass[11pt,a4paper]{book} % Packages[![enter image description here][1]][1] usepackage[left=3.5cm, right=3.5cm, top=4.3cm, bottom=4.25cm]{geometry} usepackage[utf8]{inputenc} usepackage{libertine} usepackage[libertine]{newtx...
