Reproduction Steps
I use the test case:
func testLinkingObjectObservation() {
let realm = realmWithTestPath()
let objectA = ObjectWithLinking()
let objectB = ObjectWithLinking()
try! realm.write {
realm.add(objectA)
realm.add(objectB)
objectA.objectCol = objectB
}
let ex_a1 = expectation(description: "linkingObjects should change")
let ex_a2 = expectation(description: "objectCol should change")
let ex_b = expectation(description: "linkingObjects property should change")
let a1 = objectA.observe(keyPaths: [\ModernAllTypesObject.linkingObjects]) { _ in
ex_a1.fulfill()
}
let a2 = objectA.observe(keyPaths: ["linkingObjects"]) { _ in
ex_a2.fulfill()
}
let b = objectA.observe(keyPaths: [\ModernAllTypesObject.objectCol]) { _ in
ex_b.fulfill()
}
try! realm.write {
objectA.objectCol = nil
}
waitForExpectations(timeout: 2, handler: nil)
a1.invalidate()
a2.invalidate()
b.invalidate()
}
