same for me in XCTest. If I add Host Application, AND Allow testing Host Application APIs tests build correctly. any other combinations, fails.

git the same on June 2024 on iOS18 beta

maybe is not the same.. but I got here searching a way.. from Test Flight I DO see a crash: if I download I got testflight_feedback.zip unzipping, I can see in in JSON: { "id" : "AILekJY1tZIOmVavWYVqgVE", "timestamp" : "2024-07-22T11:54:02.389Z[UTC]", "appAppleId" : 533461505, "cfBundleShortVersion" : "2.962", "cfBundleVersion" : "176", "deviceModel" : "iPhone11,8", "osVersion" : "16.3.1", "locale" : "it-YE", "carrier" : null, "timezone" : "Europe/Rome", "architecture" : "arm64e", "connectionStatus" : "MOBILE_DATA", "pairedAppleWatch" : "", "appUptimeMillis" : null, "availableDiskBytes" : 1258336256, "totalDiskBytes" : 63933894656, "networkType" : null, "batteryPercentage" : 39, "screenWidth" : 414, "screenHeight" : 896, "emailAddress" : ".......", "comment" : "Altro crash" } here is NOT a reread xcrah log.. any clue? is better to use a TSI??
