I have a fairly simple app that parses a RSS feed and shows it's content in a table view. It's available on the App Store. I have Crashlytics crash reporting integrated. I recently received two reports. These are a little difficult to decipher.
This has occurred in an iPhone 6 running iOS 10.2.1.
This is from an iPhone 5 running iOS 10.2.1.
Even though it says it's crashing due to privacy violations, I'm not accessing any services that requires permission in my app.
Also searching on com.apple.root.default-qos lead me to believe that this may have something to do with background threads. The only place where I use a background thread is to parse the RSS feed data.
DispatchQueue.global(qos: .background).async {
guard let data = try? Data(contentsOf: URL) else {
return
}
do {
let xmlDoc = try AEXMLDocument(xml: data)
if let items = xmlDoc.root["channel"]["item"].all {
self.posts.removeAll()
for item in items {
let title = item["title"].value ?? ""
// ...
self.posts.append(jobPost)
}
DispatchQueue.main.async {
self.saveposts(self.posts)
self.posts.sort { $0.publishDate > $1.publishDate }
self.tableView.reloadData()
UIApplication.shared.toggleNetworkActivityIndicator(show: false)
self.toggleUI(enable: true)
if self.refreshControl.isRefreshing { self.refreshControl.endRefreshing() }
}
}
} catch let error as NSError {
print("RSS parsing failed: \(error)")
self.showErrorAlert(error)
UIApplication.shared.toggleNetworkActivityIndicator(show: false)
self.toggleUI(enable: true)
if self.refreshControl.isRefreshing { self.refreshControl.endRefreshing() }
}
}
I tested this code on my iPhone 5 running iOS 9.3.5 and simulators running iOS 10.2 but no crash occurred.
Is there any other way to track down this problem?
